拉腊维尔5.6
我尝试通过电子邮件发送Laravel通知。我想使一些文本加粗，并放入换行符，而不使用line($text)方法带来的整个新段落。因此，我在通知类中尝试了此操作。我还尝试使用\n字符串作为新行。

return (new MailMessage)
->subject('Booking Confirmed - Please Read')
->greeting('Hello ' . $this->booking->user->first_name . ',')
->line('Thank you for booking. Here are your booking details:')
->line($this->booking->provider->providerType->name . '<br>' .
    $date . '<br>' .
    $this->booking->start_at . '<br>' .
    $this->booking->address_1 . '<br>' .
    $this->booking->address_2 . '<br>' .
    $this->booking->address_3 . '<br>' .
    $this->booking->city . '<br>' .
    $this->booking->postcode . '<br>' .
    '£' . $this->booking->price
)
->line('<strong>Need to cancel?</strong><br>' .
    'Don\'t forget to contact the provider on the details above if you need to cancel or reschedule. 
    They won\'t mind, as long as you tell them.'
)
->line('<strong>Payment</strong><br>' .
    'Pay the Service provider direct as you normally would. This keeps things simple and costs down.'
)
->line('<strong>FAQ\'s</strong><br>' .
    'Please click here for more information'
)
->line('<strong>Don\'t forget to leave feedback after!</strong><br>' .
    'Help build your relationship with your Service Providers by leaving feedback'
)
->line('We hope to see you again soon!')

我尝试过通过php artisan vendor:publish --tag=laravel-mail命令发布和不发布刀片模板，然后将{{$line}}更新为{!! $line !!}}，但没有成功。
在mailtrap

中，它会这样打印
